Enum BlobError 

pub enum BlobError {
    TooShort,
    BadMagic,
    ValidityMismatch(u32),
    TruncatedMeta,
    Decode,
    TrailingMeta(usize),
    Encode,
}

Why a blob image did not parse or encode.

Each variant carries what a caller needs to report the failure. The crate does no logging of its own: it never knows which file the bytes came from, so the caller that opened the file owns the diagnostic.

Variants

TooShort

fewer bytes than the fixed header

BadMagic

leading bytes are not the kind’s magic

ValidityMismatch(u32)

the header’s validity token is not the one the kind requires; carries the token found

TruncatedMeta

header promises more metadata than the image holds

Decode

metadata block is not decodable postcard

TrailingMeta(usize)

metadata decoded without reading the whole block; carries the number of bytes left over

Encode

metadata could not be serialized
